1. A 2. D 3. C 4. B are the answers
Answer: Electricity and magnetism are essentially two aspects of the same thing, because a changing electric field creates a magnetic field, and a changing magnetic field creates an electric field.
Answer:
Acid ammonium carbonate // Ammonium bicarbonate.
Explanation:
Hello, a 4 is missing in the fist H, thus:
The presence of the hydrogen between the ammonium and the carbonates characterizes the salt as an acid salt, so you could name it as acid ammonium carbonate or ammonium bicarbonate (similar to the sodium bicarbonate which is .
Best regards.
Answer:
[A] + [B] decrease rapidly.
[CD] increases rapidly.
Explanation:
<em>A + B → CD,</em>
The reaction proceeds that A reacts with B and their concentration decreases to produce CD that its concentration increases with time.
At the beginning of the reaction; the concentration of A + B decreases rapidly and the concentration of CD increases rapidly.
<em>Kindly, see the attached image.</em>

[A] + [B] decrease rapidly.
[CD] increases rapidly.
This chemical reaction should follow the Law of Conservation of Mass where mass cannot be created nor destroyed. That is, what goes in a system should be equal with what goes out the system. For this problem, the mass of C that is produced assuming there are no by-products should be 600 pounds.
